Roommates Ricky Berry and Philip Blackwell told WRIC that upon entering the Carytown CVS they asked a worker if the store sold sliced cheese, which it did not.

Only moments later, Berry and Blackwell couldn't find any employee in the store. After about a half an hour, a police officer showed up, notes WGHP.

The workers, who had called authorities, were found in a locked room.

Soon after, the officer told the customers they had to leave or face trespassing charges.

CVS has apologized and says it is investigating the situation.
